FTP is the maximum wattage an athlete can sustain for 60 minutes and according to Dr. Andrew Coggan, “the single greatest determinant of cycling performance”1. FTP has recently come under attack on ‘the internet’ but I can assure you its utility, principles and theory are alive and well.
Not many people in the world have an FTP power to weight ratio close to Geraint Thomas or Sepp Kuss, but all athletes can improve their performance from raising their FTP. Long climbs, solo breakaways, and time trials all rely directly on an athlete’s FTP. It might not seem like FTP has much bearing on ability to sprint, but it very much does. FTP almost can be thought of as a sponge. The higher this number is, the bigger their sponge is, and the more efforts athletes can absorb. Every time a race goes hard, it will take less out of the athlete with the higher FTP, and in return they will have more energy left in the tank for a big selection or for the sprint at the end. Training FTP is important for all cyclists.
Before you Train your FTP you gotta know your FTP, here’s how:
So now that you know how important FTP is you’re probably running out the door to improve it as fast as possible. Before you go out and start hammering away, you should perform a field test to learn what your current FTP is.
There are a couple ways to establish your FTP: a blood lactate test, a MLSS test, a sustained 60 minute effort, or a good old fashioned easy to do and replicate 20 minute field test. There are a few different procedures, but the one I recommend goes as follows:
First, warm up for 20 to 30 minutes starting with easy pedaling and progressively building to more zone 2 endurance pressure on the pedals. Then, on a stretch of road with no interruptions (most often this is a sustained climb) go for 20 minutes at your maximum pace. From this 20 minute test we take 5-10% off of the average power and use that as your FTP.
1. Sub-Threshold/Sweet Spot Work
“Sweet Spot” occurs at 84 to 97 percent of your FTP and riding here can help improve the aerobic, steady state efforts that characterize FTP. Sweet Spot gets it’s name because it is a balanced amount of intensity and volume. You can achieve more positive physiological adaptations than if you were to ride harder at zone 4/threshold. By riding below your FTP it is a more repeatable workout and won’t take quite as much out of you. Do these efforts on a stretch of road without interruptions, and focus on maintaining a steady effort. A steady grade 3 to 5 percent hill works very well.
2. Threshold Climbing Work
To improve performance on long climbs, do efforts at 100-110 percent of FTP on a sustained climb. Ideally, the power for the efforts should be the maximum power that can be sustained for each interval in the set, without dropping power from the first effort to the last. These training days are difficult and are most effective if done at quality power, so do them on days when you are fresh and can afford to dig deep. A good session of threshold work should not include more than 60 minutes spent at threshold, so piece out the intervals to stay under this limit.
Start with 3×10 minute efforts at 100-110 percent of FTP with 10 minutes of easy spinning between efforts.
Build up to 3×15 minute efforts at 100-105 percent of FTP with 8 minutes of easy spinning between efforts. The “gold standard” FTP workout is 2×20 minute efforts at 100-105 percent of FTP with 10 minutes of easy spinning between efforts.
As a bonus workout, to train for longer road events and being able to perform strongly at your FTP at the end of a hard race, rather than doing FTP efforts as a set, do them spaced throughout a long endurance ride. For example do 3×15 minute climbing efforts over the course of 5 hour ride, 1 hour into the ride, 2.5 hours into the ride, and 4 hours into the ride. The goal is to get to the point where you can do the third effort at 4 hours into the ride at the same power as the first effort 1 hour into the ride.
3. Flat Land FTP Work
Don’t fall into the trap of only doing threshold work on climbs. Climbing threshold work is great, but it is easy to get to a point where you can only put out your best FTP numbers on a steep gradient and are floundering on the flats. To prevent this, all the same climbing FTP workouts can and should be done on flats at 95+ rpm as well. If the terrain allows it, when doing FTP sets, I recommend doing one of the three efforts on a flat road and two on a climb. The flat land FTP work is also a good place to get in time on the time trial bike.
Now that you know how to best improve your FTP, review your power files for the improvements. You can look at peak 20 minute average power from hard rides and races, as well as peak 60 minute Normalized Power®. You may see yourself breaking these records on climbs, group rides, time trials, breakaways, or the end of a race. Also, a few months after your initial field test, do another identical field test to track the improvement and update your training zones from your new and improved FTP.
